What analysis tool shows information flow by tracing data from its origin through processing, storage, and output?

The analysis tool that shows information flow by tracing data from its origin through processing, storage, and output is called a Data Flow Diagram (DFD).

Here are the steps to create a DFD:

1. Identify the system: Determine the boundaries of the system that will be represented in the DFD. This could be a whole system or just a part of it.

2. Identify the entities: Entities are the external elements that interact with the system. They could be users, other systems, or data sources.

3. Identify the processes: Processes are the activities that transform the data in the system. They could be calculations, data transformations, or other operations.

4. Identify the data stores: Data stores are places where the system stores data. They could be databases, files, or other storage devices.

5. Identify the data flows: Data flows are the paths that data takes through the system. They show how data moves from entities to processes, from processes to data stores, and so on.

6. Draw the DFD: Use a diagramming tool to draw the DFD. Start with the entities on the outside, then draw the processes in the middle, and the data stores in between. Connect them with arrows to represent the data flows.

7. Review and refine the DFD: Check the DFD for accuracy and completeness. Make sure it represents all the data flows in the system, and that it doesn't include any unnecessary details. Refine the DFD as needed until it accurately represents the system.
